Title: Improvements in apparatus for teaching music
IPC: G09B15/08
Filed: 1920-03-02
Abstract: 139,777. Schantz, E. M. Aug. 11, 1917, [Convention date]. Chord and note indicators; teaching music. -The piano or other instrument at which the pupil is seated is connected electrically or pneumatically to a keyboard operated by the teacher so that a visible sign is given above the notes which the pupil has next to play. The use of pedals, metre, rhythm, &c., can also be signalled. Fig. 2 shows diagrammatically electric connexions from the teacher's keyboard to lamps placed above the notes on the pupil's instrument. Fig. 3 shows a vertical section of the lower part of the teacher's instrument. Fig. 7 shows an enlarged view of the indicating means on the pupil's instrument. Fig. 10 shows means for actuating the signals mechanically from another part of the pupil's instrument. Preferably, the indicating means, such as the lamps 26<a> and 26<b>, Fig. 7, are placed beneath a representation of the staff showing the written note in each instance, and the lamps 26a corresponding to the black notes are placed in an upper row, and are distinguished by coloured glass. In the arrangement shown in Fig. 2, the keys 18 of the teacher's keyboard, which may or may not form part of an effective piano, have plates 33 which make contact with the plate 35 when the keys are depressed, the circuit from the battery 39 passing through the connexions 50, 38, 37, 35, 33, 47, 44, 43, to the lamps 25. The circuit may be interrupted by the switch 50. And, when desired, the switch 57 can be closed, by means of a pedal, to energize the special lamp 54 used for indicating metre, rhythm, pedal control, or other matters according to any prearranged scheme. In order that certain signals may remain permanently on, when desired, pedals 66, 67, 68, Fig. 3, which co-act with stops 69, 70, 71, are used to alter the position of the bar 36 carrying the common contact-plate 35 so that (1) the plates 33 may spring past the lower edge of the plate 35 when the keys 18 are depressed and maintain contact on the other side when the keys are released, (2) when desired some of such contacts may be released by the corresponding keys being again depressed when the pedal 67 is in operation, or (3) all such contacts may be released together by operating the pedal 68. When pneumatic means are employed for actuating the signals, these latter may be constituted as vertically movable bodies which are hidden by a bar when in the inoperative position. The mechanical means for operating the signals, shown in Fig. 10, consists of a series of lever arms 88 mounted on pivots 89, and at one end carrying balls or disks 87, the other ends being supported by small weights 90 which rest on the kevs to be actuated by the teacher.

Title: Improvements in compressed laminated fibrous products and process of making the same
IPC: B27D1/04
Filed: 1928-02-29
Abstract: 299,442. Sprucolite Corporation, ;Assignees of Ollesheimer, L. J.). Oct. 28, 1927, [Convention date]. Veneers.-In the production of laminated articles by submitting lavers of fibrous material such as wood coated with a binder, and preferably arranged with the grain of adjacent layers crossing, to pressure, the article is submitted to a pressure greater than that required to compress it to the desired extent until the binder has acquired an initial set : the pressure is reduced to the extent necessary to allow the article to expand to the desired size, and the pressure is maintained until the binder is permanently set. A stack of spruce boards P coated with a casein glue is mounted between metal beams B in a hydraulic press H. Pressure is applied to compress the stack from say 37 in. to 24 in., as shown in dotted lines. When the glue is partially set, the pressure is released to allow the stack to expand to 26 in. Clamps are put on the beams B and tightened to maintain this pressure, and the stack is removed from the press. By this process, the binder is said to penetrate into the pores of the wood, and the tendency to " spring back " is largely eliminated. Specification 299,441 is referred to.

Filed: 1957-02-28
Abstract: 807,364. Door fastening. MINER Inc., W. H. Feb. 28, 1957, No. 6697/57. Class 44 A combined latch means and door fasteners for hinge supported door structures having a pair of door members 13, 14 connected for relative swinging movement by a hinge member 21 or 22 and pivotally connected hinge leaves 23, 24 fixed, respectively, to said door members is characterized by a keeper engaging member C integral with the hinged leaf 24, a keeper member D having a laterally opening pocket 48 within which the member C is engageable to force the door member 14 open and closed, a sliding latch element B mounted on the hinged leaf 23 and a co-operating catch element for said latch element on the keeper member. Each hinge leaf has a plurality of eye members connected together by a pin 27 and the member C is formed integral with the lowermost eye member 26, it consists of a radial arm 28 having a crank pin 29 at its outer end which is engageable with the pocket 48 of keeper member D so that when the door member 14 is swung inwardly towards closed position the pin 29 engages the pocket 48 and cams the door member 13 closed. The latch element comprises a head 35 of substantially square cross-section which fits within a sleeve 30 and which is urged to its engaging position by a spring 38. The weight of the head 35 is sufficient however in case of spring failure to work by gravity. The lower end of the head 35 is bevelled to present an upwardly inclined underneath surface 39 so that when the door member 13 is moved to closed position the surface 39 engages a cam face 54 on the catch element to retract the head; after the head clears the face 54 it is projected into a passage 52 by gravity or the spring 38 and must be manually lifted to clear a wall 53 before the door member 13 can be opened more than a limited extent.

Title: Improvements in and relating to photographic film-advancing mechanisms
Inventor: TYLER FRANK
IPC: G03B1/38
Filed: 1956-03-02
Abstract: 814,079. Photographic film-advancing mechanism KELVIN & HUGHES Ltd Feb. 15, 1957 [March 2, 1956], No. 6719/56. Classes 98(1) and 98(2) Photographic film-advancing means which includes a sprocket engaging film perforations, a mechanism coupled to the sprocket to determine the extent of its angular movement for each rotation of a driving member, a friction clutch which, when actuated, couples the driving member to the shaft of a continuously-rotating motor, and electro-magnetic means for intermittently actuating the clutch, is characterized by a cam-operated switch by which a condenser is charged during part of each revolution of the cam and, at a point in the revolution of the cam, discharged through the clutchoperating electromagnetic means. The mechanism is particularly intended for use in the apparatus described in Specification 814,080, including a shaft 10, Fig. 2, for every rotation of which the film is advanced. A cam 23 on the shaft 10 has a step 24, and moves a contact-bearing arm 22 of a switch 11 between fixed contacts 25, 26. The switch 11 is connected in a circuit shown in Fig. 1 so that when arm 22 is in contact with contact 25, a condenser 12 (bridged by a high resistance 14) is charged from a source of potential 13. When step 24 passes arm 22, the arm moves from contact 25 to contact 26, so that the condenser discharges through a solenoid 15. As shown in Fig. 3, a film sprocket 28 is mounted on the shaft 29 of a Maltese cross 35, operated by a cam 36 and a pin 40. An electric motor drives a worm wheel 45 continuously through a worm shaft 44. Wheel 45 is bolted to a sleeve 46 freely mounted on a main shaft 42 by roller bearings 47. The shaft 42 may be connected to sleeve 46 by a one-revolution clutch consisting of a coil spring 50 surrounding the sleeve and anchored at one end to a cam 48 on the main shaft 42, and at the other end to a cam 19 rotatable on sleeve 46. Normally the clutch is held inoperative by an arm 52, which engages cam 19 and is mounted on an armature 16 of solenoid 15. When the solenoid is energized, armature 16 rocks on its pivot 17 to release cam 19. The clutch operates to drive shaft 42 one revolution, after which cam 19 is again engaged by arm 52. This rotates cam 36 and Maltese cross 35 to turn the sprocket a quarter of a revolution. The inertia of the parts driven by shaft 42 causes it to overshoot until spring 50 is loose on sleeve 46. It is prevented from tightening by a pawl 53 which engages cam 48.
